I just added a new module to KStars/Ekos named Analyze.
Analyze is now available in the latest KStars source, will be available in nightly builds in the next day or two, and will be part of the next KStars release.
This is "V1.0". I'm sure there are improvements to be made, new features, and perhaps bug fixes. I'm hoping some of you will experiment with this, let me know how its going, and feedback ideas for improvements on this thread.
Here's a screenshot.
Analyze helps you understand how your imaging session is going. In the above picture, Analyze is reviewing an old imaging session from 8/22/2020 starting at 21:27:04 (see the display at the top). It shows there were 32 captures, first 8 green, then 8 blue, 8 red, and 8 green. There were several auto-focus sessions, several guiding sessions (interrupted by dithering or focus), You can see the guide drift-plot from the 3rd blue capture in the lower right, which was generated by clicking on that blue capture. The Statistics plot is showing a graph of SNR (yellow), RMS Guide Error (red), and Captured Image HFR (blue) for the imaging session which started around 21:27 and lasted until about midnight, or alternatively, about 9600 seconds long. The Details window in the bottom left is showing more information about that 3rd Blue capture.
The Help button doesn't seem to lead to a link that works properly at this point (hopefully that'll be fixed soon) but the information there is pretty much what I've included in this forum post.
More details below.
Introduction
The Analyze Module records and displays what happens in an imaging session. That is, it does not control any of your imaging, but rather reviews what occurred. Sessions are stored in an analyze folder, a sister folder to the main logging folder. Analyze can display data from the current imaging session. Alternatively, the .analyze files written there can be loaded into the Analyze tab to review an old imaging session. In this way, Analyze is similar to the left-most "setup" tab which shows progress and status of the current session, but Analyze shows much more information about what's happened, and can review old sessions.
Analyze has two main graphs, Timeline and Stats. They are coordinated--they always display the same time interval from the Ekos session, though the x-axis of the Timeline shows seconds elapsed from the start of the log, and Stats shows clock time. The x-axis can be zoomed in and out with the +/- button, mouse wheel, as well as with standard keyboard shortcuts (e.g. zoom-in == control +) The x-axis can be panned with the scroll bar as well as with the left and right arrow keys. You can view your current imaging session, or review old sessions by loading .analyze files using the Input dropdown. Checking Full Width displays all the data, and Latest displays the most recent data (you can control the width by zooming).
Timeline
Timeline shows the major Ekos processes, and when they were active. For instance, the Capture line shows when images were taken (green sections) and when imaging was aborted (red sections). Clicking on a green section gives information about that image, and double clicking on one brings up the captured image in a FitsViewer, if it's available. [Note: if you've moved your captured images, you can set alternate directory in the input menu to a directory which is the base of part of the original file path.] Clicking on a Focus segment shows focus session information and displays up the position vs HFR measurements from that session. Clicking on a Guider segment shows a drift plot from that session, (if it's guiding) and the session's RMS statistics. Other timelines show status information when clicked.
Statistics
A variety of statistics can be displayed on the Stats graph. There are too many for all to be shown in a readable way, so select among them with the checkboxes. A reasonable way to start might be to use RMS, SNR (using the internal guider with SEP Multistar), and HFR (if you have auto-compute HFR in the FITS options). Experiment with others. The axis shown (0-5) is appropriate only for ra/dec error, drift, rms, pulses, and hfr. These may be y-axis scaled (awkwardly) using the mouse wheel, but the other graphs cannot be scaled. To reset y-axis zooming, right-click on the Stats plot. Clicking on the graph fills in the values of the displayed statistics. This graph is zoomed and panned horizontally in coordination with the timeline.
